RF Hardware Engineer - Multi-Radio Coexistence

You will be responsible for assessing multi-radio coexistence performance across Apple's wireless ecosystem. This role involves hands-on hardware engineering, cross-functional collaboration, and data-driven validation to ensure seamless coexistence across a diverse range of radio technologies. You will work closely with RF Test Engineers, chipset teams, and cross-functional partners to identify, debug, and resolve coexistence challenges — from early design stages through final Performing HW failure analysis at the RF/wireless system level to identify low-margin or failing behaviors, leveraging hands-on experimental hardware modifications. Proposing design and process changes to address multi-radio coexistence issues, considering design constraints and aligning with cross-functional partners on trade-offs and implementation paths. Reviewing designs and signing off on releases of PCB layouts, flex layouts, system-level grounding, shielding, and related components. Executing validation and characterization test plans to meet multi-radio coexistence performance targets. Tracking validation status, analyzing results, and communicating actionable insights from data. Evaluating multi-functional change requests, updating characterization plans as needed, and surfacing any emerging issues. Collaborating with RF Test Engineers on device bring-up, test setups, and test procedures for multi-radio coexistence validation. Performing experiments using hardware mock-ups, system prototypes, and experimental setups. Partnering with cross-functional teams on circuit-level and system-level simulations to identify risk areas and drive root cause analysis. Designing performance-based test setups and benchmarks to evaluate multi-radio coexistence across a range of coexistence scenarios. Bachelor’s degree in electrical engineering with 10+ years relevant work experience. Experience with at least one radio technology: Cellular, GPS, Bluetooth, Wi-Fi, Thread, NFC, or UWB. Knowledge of RF component characteristics and proficiency with lab equipment including spectrum analyzers, network analyzers, signal generators, and oscilloscopes. Knowledge of wireless architectures including front-end design, antenna sharing, and link budget line-up. Ability to travel domestically and internationally up to 20%. Strong written and verbal communication skills. Solid understanding of fundamental antenna theory. Master’s degree in electrical engineering with 10+ years of relevant work experience. Proven understanding of RF hardware and best practices for system-level grounding, shielding, isolation, and electromagnetic interference mitigation. Experience in performing hands-on disassembly and system-level debug at the module, reference board, or system level. Experience in debugging and optimizing conducted or radiated radio systems. Experience in antenna design and EM simulation.
